Adjusting clamp for eccentric shaft

Abstract

The invention discloses an adjusting clamp for an eccentric shaft. The adjusting clamp comprises a three jaw chuck and a clamp body; the clamp body comprises an elastic adjusting device and a vertical connecting plate, wherein the three jaw chuck is located at one side of the vertical connecting plate, another side of the three jaw chuck with a bolt hole is connected with the vertical connecting plate by a bolt, and the upper part of another side of the vertical connecting plate is connected with an elastic adjusting device in a sliding manner; the lower part of another side of the vertical connecting plate is provided with a limit plate and an adjusting block connected with the limit plate in a sliding manner, the limit plate and the vertical connecting plate are vertically and fixedly connected, the adjusting block is located above the limit plate, a centre is embedded in one end of the adjusting block far away from the vertical connecting plate and the point of the center is toward to one side of the vertical connecting plate; a locking bolt is arranged below the adjusting block, and the locking bolt penetrates through the limit block and is propped against the lower end of the adjusting block. According to the adjusting clamp provided by the invention, the defects that an axial lead needs to be changed in the process of processing an existing eccentric shaft, the operation is complicated and the efficiency is low can be overcome, therefore the adjusting clamp for the eccentric shaft which is simple to operate and high in efficiency is provided.

Description

technical field [0001] The invention belongs to the processing field of transmission devices, and in particular relates to an adjustment fixture for an eccentric shaft. Background technique [0002] Eccentric shaft, as the name implies, its center is not in the center of the axis. A common eccentric shaft has multiple shaft centerlines. In the usual long shaft with a center line, during grinding, the two ends of the shaft are usually fixed and clamped by the chuck, and the two ends are positioned and supported by the top, so that during the processing, the two ends The connection line between the tops of the ends coincides with the center line of the shaft, so that during processing and grinding, the shaft body rotates and grinds along the axis line to avoid deviation of the axis line. The fixed center can support the shaft blank with complex end face and the shaft that does not allow to drill the center hole. The top is mainly composed of a thimble, a clamping device, a ...
